INn FOUR hours Jennifer will travel 12 m/h x4 = 48 miles

  it will take Thomas  48 miles / 4 m/hr = 12 hours to reach the bike

    in the meantime Jennifer has EIGHT hours of walking   3 m/hr x 8 =  24 miles form the bike

        Thomas now sets out at   10 m/h    this is     10 - 3 = 7 m/h faster than Jennifer is walking

             he will close the 24 miles and catch Jennifer in  7 m/hr *x =  24 m

                     x =  24/7hours

So Thomas walks for   12 hours then bikes for  24/7 hr   =  15  3/7 hrs  = ~ 15 hr 26 min

Just put in 108 fr 'y' in your equation ...then solve for 't' using quadratic formul or factoring.... throw out any negative values for t

108 = -6t² + 51 t

-6t²+51t - 108 = 0     now use quadratic formula or factoring to find the values of 't'

AC=?? in

Back square is  9km x 5 km =......

triangular ends are 3-4-5 rt triangles and there ae TWO  so     2   x 1/2 x 3 x 4 =.......

top rectangle    9 x 3  = .......

front rctangle    9 x 4 = ........                  ADD all of the REDs

120^o   x  pi /180^o = 2/3 pi Radians   

2/3 pi x 10(2)  = 20 pi /3                  [ 10(2) is the diameter]

 x -2<3x+4<13     subtract 4 from all three terms

x-6 < 3x <  9         subtract x from the t L terms

-6 < 2x       and     3x< 9    divide right by 3   and L by 2

-3 < x      and    x <3                   sooooo   

  -3 < x < 3

(I edited this because my answer got truncated off for some reason)

Here is a scan solving w/out a calculator:

Find the slope of the line, m    = rise/ run =   (y1-y2)/(x1-x2)

    then put into this equation   y = mx + b

      THEN substitute in one of your points into the equation to calculate the value of 'b'

                    then you line equation is y = mx + b

Opposite angles of two crossing lines are equal    so 135 = 81 + DC      DC = 54

     a straight line is 180      so     81 + 54 + EF = 180     EF = 45          as is BC

         CFD = 45 + 45 + 135 + 81 = ........

I am not sure of this answer

    if range of f is   from   y = -5 to 3

       multiplied by the range of g        the largest would be   -5 * -2 = 10

           the smallest would be 3 * -2 = -6

               so I THINK the new range would be      [-6,10]        b=10

                     please let me know if I am correct or incorrect....I need to learn too!
